When Jesus declares that He is the Light of the World, He is telling us that He is God and that we must follow Him if we want eternal life and an abundant life on earth. His definition of abundance is not the same as the world's definition. Rather, He tells us that true abundance is to know Him and to be set free from sin; the best this life has to offer is a life with Christ. Jesus promises that all who believe in Him, repent of their sins, and follow Him will not only receive eternal life, but a life of fullness.
